Project Name:

Walton Camp 550 Microgrid Construction

Project Location:

Kandahar Airfield (KAF), Afghanistan


U.S. Army Corps of Engineers (USACE) – Philadelphia District

Client Needs and Requirements:

The existing electrical infrastructure at Walton Camp 550 consisted of small spot generators on each structure in the camp, and they were no longer meeting the growing power needs of the camp.  In addition, the power infrastructure was not per NEC standards which was creating potential Life, Health, and Safety (LHS) hazards for our Special Forces personnel.  The requirement was to assess the power demands, design a capable microgrid system that would provide high availablity and mission critical power support.

Challenges and ISI’s Response:

The project required installing a new power generation and power distribution system throughout the entire base.  This meant excavating and installing power cabling to each building and strucutre in the camp.  Since this was a Special Forces operation, many of the personnel worked at night and slept during the day, so we were tasked with minimizing disruption to personnel who were sleeping during our normal working hours.

ISI took extensive measures, at our own cost, to change working methodologies to reduce noise.  This included extensive amounts of hand excavation instead of using large machinery in an effort to reduce the noise we generated during this project.

The Results:

The project was extremely successful and completed on time and on budget.

The Details:

ISI installed the following to meet the client’s requirements:

  • Evaluation of the base power demands
  • Design of a highly reliable and available power generation system
  • A 100% redundant 750kW microgrid system was designed and installed
    • two 750kW 480v diesel generators were installed in a redundant configuration which fed a pair of 1000kVA 480v to 4160V transformers
  • Integration to the Military 4160V SDC distribution equipment which fed all of the structures and facilities
